A settling chamber is measuring 6 meters in length, 3 meters in width, and 1.5 meters in height. The air stream flowrate entering the chamber is 17 m3/s, and the average particle size (diameter) is 65 micrometers. Assume a particle density of 1800 kg/m3 and that Stokes law applies. Some properties of air: Atmospheric pressure = 101.4 kPa = 14.7 psi Air density = 1.2 kg/m3. Air viscosity = 1.85x 10^-5 Pa.s. the air stream horizontal velocity in the chamber...

Very small objects, such as dust particles, experience a linear drag force, D⃗ D→ = (bv, direction opposite the motion), where b is a constant. For a sphere of radius R, the drag constant can be shown to be b=6πηR, where η is the viscosity of the gas. Suppose a gust of wind has carried a 52-μm-diameter dust particle to a height of 260 m. If the wind suddenly stops, how long will it take the dust particle to settle...

In addition to the buoyant force, an object moving in a liquid experiences a linear drag force Fdrag = (bv, direction opposite the motion), where b is a constant. For a sphere of radius R, the drag constant can be shown to be b = 6πηR, where η is the viscosity of the liquid. Consider a sphere of radius R and density ρ that is released from rest at the surface of a liquid with density ρf. a. Find an...

A small rocket probing the atmosphere has a length of 3 m. It is fired vertically upward through the atmosphere, its average velocity being 1000 m/s. Consider the flow over the rocket at this average velocity at altitudes of 30,000 and 80,000 m. Can the air flow over the rocket be assumed to be continuous at these two altitudes? At an altitude of 30,000 m, the air has a temperature, pressure, and viscosity of ?55°C, 120 Pa, and 1.5 ×...

12) There are several types of drag on a car other than air resistance. Effects having to do with the squeezing of the tires (rolling resistance) and frictional forces in the drivetrain (the system that transfers energy from the engine to the rotation of the wheels) also must be taken into account. Engineers use the following equation to model the total force due to these different effects Fdrag=A+Bv+Cv^2 For a Camry, these coefficients are estimated to be A=117.130 N, B=1.800...

1. When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 913 N and the drag force has a magnitude of 1079 N. The mass of the sky diver is 93.2 kg. Take upward to be the positive direction. What is his acceleration, including sign? 2. The space probe Deep Space...
